It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-40066 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-40066/ (Markdown: https://insights.sbomify.com/CVE-2025-40066/index.md)","id":"CVE-2025-40066","markdown":"https://insights.sbomify.com/CVE-2025-40066/index.md","name":"CVE-2025-40066","record":{"aliases":["BELL-CVE-2025-40066","DEBIAN-CVE-2025-40066","GHSA-8r3f-48gc-phmq","UBUNTU-CVE-2025-40066"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A missing null check in the mt7996 WiFi driver can cause a kernel crash, leading to denial of service for local or adjacent attackers.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7996: Check phy before init msta_link in mt7996_mac_sta_add_links()\n\nIn order to avoid a possible NULL pointer dereference in\nmt7996_mac_sta_init_link routine, move the phy pointer check before\nrunning mt7996_mac_sta_init_link() in mt7996_mac_sta_add_links routine.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"wifi: mt76: mt7996: Check phy before init msta_link in mt7996_mac_sta_add_links()","id":"CVE-2025-40066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"fs/ntfs3: reject index allocation if $BITMAP is empty but blocks exist","id":"CVE-2025-40067"},"packages":[],"prev":{"headline":"RISC-V: KVM: Write hgatp register with valid mode bits","id":"CVE-2025-40065"},"products":["Linux"],"published":"2025-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing null check in the mt7996 WiFi driver can cause a kernel crash, leading to denial of service for local or adjacent attackers.","url":"https://insights.sbomify.com/CVE-2025-40066/"}
